Неодимовые магниты кольца похожи дисков или цилиндров, но с центральным отверстием. Most neodymium ring magnets and tube-shaped magnets are axially magnetised: Северный и южный полюса расположены на плоских круговых поверхностях (“Верх и низ”). The few diametrically magnetised neodymium ring magnets with poles “Лево и право” специально помечены.

Due to their shape, it is very tempting to screw-mount ring magnets. But please keep in mind, the material is very brittle and chips easily. That is why we advise against the screw-mounting of ring magnets with holes. It is much safer and easier if you use screw-on magnets или countersunk pot magnets.
